Investigating load-duration and environmental conditions on the mechanical behaviour of timber connections using X-ray non-destructive testing (Research)

With the growing emphasis on sustainable construction, timber is emerging as a preferred material for mid- and high-rise buildings. However, these structures face significant challenges due to load variations and fluctuating environmental conditions, which can lead to local defects in timber which impact connection behaviour. These vulnerabilities compromise the structural integrity of connections over time, and current literature provides insufficient insights into the long-term behaviour of timber under such conditions. This gap in knowledge raises concerns that some existing timber structures may fail to meet safety standards throughout their intended service life. To address this critical issue, this project investigates the effects of creep and mechano-sorption on the performance of timber connections. By employing advanced nondestructive testing methods, such as X-ray scanning, the study aims to capture the intricate changes in connection behaviour under varying loads and environmental influences. This research will not only enhance our understanding of timber's long-term performance but also provide actionable insights for designing safer, more durable structures with extended service lifespans, supporting the transition toward sustainable construction.
